JACOB KRQNHEQIMQ or--er. nvnnniqn, on o seam AT R rrow FOB CHAIRS; 'c fier e Application med February 18, 1931; Serial no; 5,553, a

My invention relates to an improvement in resilient seats and bottoms- 'fo'r chairs, couches and the like, and in general my ob-, ject'is to provide simple and effective means 5' and devices for attaching and suspending A a flexible bottom by means of a-set of coiled springs yieldably- Withina suitable frame, such as a rigid chair or couch frame.

' In carrying out my general object, I em- 19 ploy brackets, clips or hangers which enable the bottom member to. be attached to a rigid frame a facile way and under a fixed tension but with freedom to move vertically within limits" when suspended from said bodying a flexible bottom and my improve.

ment, and Fig. 2 is a sectional view vertically of the same structure, the compression or upholstery springs. being omitted over a part ofthe flexible bottom; Fig. 3Iis a perspective view of a corner portion of a frame and flexible bottom, including a modified form of bracket and .suspensory support therefor, and Figs. 4 and'5 'are'horizontal vertical sections ofthesame. Fig. 6 is a perspective view of a further modified form o f'attachment bracket, I Now, referring to Figs. 1 and 2, the invention as shown therein comprises an open rectangular frame A made of wood or other material, within whicha flexible or pliable bottom or base memberB made of woven textile material or materials such as canvas or burlap is tightly stretched. The dimensions of bottom pieceB correspond closely to theinner dimensions of frame A to practically filland close the rectangular opening, beingjattached at its seamed border edges tofa series of angular brackets or hangers O which are nailed or screwed at spaced inter; valsto the inner sides oflframev A. The

hemmed or seamed border portions of bot tom member B contain a re-enforcin'g wire 2 which connects with the hangers or brackcits C, the goods being pierced by the hanger or; cutaway in part to receive the hanger, and the wire beingfree-to slide vertically Y in engagement with the main body or verti cal keeper portion 3 of the hanger where spaced apart from fframe A; As shown in Figs. 1 and 2, each hanger C is made of a flat strip ofmetal whichis bent at right angles at one end to provide a lower arm 4L having a perfor-ated extremity adapted to be nailed to the bottom edge of frame A, and the upper end of the ver-tical'keeper portion 3 of this hanger is also bent at. right angles and thence upwardly to provide a shorter angular extremity 5 which is perforated topermitit to be nailed against the inner side or verticalflat face'of frame A.

'The wired edge of bottom member B is adapted to move or slide vertically within the keeper portion of'each bracket or hanger G, butnormallyjbottom member B is maintained-ina raised position therein by a set of coiled suspension springs D whichhang downwardly or are suspended from hooks, staplesor loops6 aflixed to or projecting inwardly from the side railsof frame A, see Fig. 1'. Eachspring D or amultiple num-' ber of them will support a load yieldingiy and locally in the region of thespring or a series ofsprings but the lateral pull or strain on the fabr-ic'bottom member B is mainly carried or borne by the brackets C, said bottom flexing in some degree however in its body, portion-under the load and the load being also resilientlysupported by the compression-springsEbanked or grouped upon bottom member B. According-to old and es tablished upholsteri-ng practices a covering of flexible material, padded upholstering or a cushion F is-placed over the tops of springs E, andthese springs partially compressed or placed under tension'by fastening or tieing them or the covering to frame A. Thus the seating springs E and the suspension springs D- co-act to keep the covering or upholstering under tension andin shapely condition, and both sets of springs co-operate also in providing the desired soft resiliency for-seating purposes, and ease and comfort being furthered still more by some additional yield in the fabric bottom member B itself.

. "Now referring to Figs. 3 to 6, sheet 2 of theldrawings, a somewhat simpler and more compact form of the invention fisshown spaced sufficiently apart therefrom to perunit; the suspensorysprings D to be confined o'r housed between the rail and the vertical keeper portion 8 of the bracket. Openings 9 in upper arm 7 permitspring ,D to be hooked thereto and suspended therefrom, and the lower hooked-end 1.0 of the spring is connected to the border wire 2 of bottom member A, which wire fpasses through the keeper space of bracket Gto hold this flexible bottom member stretched and under tension but also free to move vertically within the keeper or bracket under controlof suspension springs D. In this form'of'suspenand each spring is always housed or covered by the bracket to prevent obstruction Orrinterference with the expanding and contracting movements of its coils. Bottom member B and the brackets .and suspension spr ngs may also all be conveniently assembled as a unit and quickly and readilyalfixed within frame A with; a. minimum of labor and exense- I V 1 c In Fig. 6, I show abracket G corresponding to'the bracket shown; in Figs. 3 to 5,

but having a reenforcing rib-or channeled. I offset 11 in itsvertical keeper portion-12. Further modifications might be made therein either to strengthen the same or to facilitate the hanging or movement of suspension spring D and border wire 2 therein. What I claim, is: g V

1. A resilient seat or bottom for chairs, couches, etc., comprising a'main frame, a flexible bottom member jwithin said-frame spaced from the innerwalls thereof, a rigid border surrounding said bottom member, coiled springs suspended from said frame and connected with said rigidborder of said bottom member, and means for maintaining said flexible bottom member under tension and stretched and axially aligned withvrespect to said frame independently of said springs. l l

2. A resilient seat or bottom for chairs, couches, etc., comprising a main frame, coiled springs suspended vertically from said frame, a flexible bottom member within .yield'ingly within said frame.

said frame spaced from the inner walls thereof and supported for vertical move ment within said frame by said springs, and tension-applying means for all sides of saidbottom member connected to said frame.

3. A resilient seat or bottom for chairs, couches, etc., comprising a main frame, a flexible bottom member and suspension springs therefor connected with said frame, and'hangermeans fixed to said frame and slidably interengaged with all sides of said f bottom member for guiding and stretching said flexible bottom member within said.

frame.

fl. A resil ent seat or bottom for gchai'rs, couches, etc., comprising a main frame, a

flexible bottom member having astifiening border wire, suspension springs connecting. said border wire with sa1d frame,-and'metal:

keepers attached. to said frame for confining said border wire movably in respectto said frame.

5. A resilient seat or .bottomfor chairs,

couches, etc., comprising a frame having an-v V gular hangers aflixedthereto, a wired'bottom member made of flexible material slidably connected with said hangers,and suspension springs for supporting sald bottom member 6. A resilient seat or bottom fer couches, etc., comprising'an' open frame havs ing angular brackets affixed to all itslnner sides, springs supported by said brackets,

and a flexible bottom within said frame spaced from the inner walls thereof,ffc'on-v nected with said springs and slidablyinter engaged with said brackets i 7. A resilient seat or bottom"f,,or 'chairs,

couches, etc., comprising an open frame;

brackets. secured to all inner. sides of said frame, springs suspended from said brackets, and a flexible bottom having a reenforced portion' connected with said springs'and s'lidably interengaged with said brackets. f n 8. A resilient seator bottom for chairs, couches, etc., comprising a frame, metal brackets at the inner sides of said frame, a flexible bottom made of woven fabric hav} ing a border seam'containinga re-enforcingi wire slidably connected. with said brackets,

and suspension springs'for said bottom supported by said bracketsif v '9. A resilientseat or 'bottom for chairs,

couches, etc., comprisinga frame having an gular brackets affixed thereto, a flexiblesheet attached at its edges to said brackets and held under tension thereby within .said frame, suspension springs. supporting said sheet for vertical movement in respect to said frame and brackets, and cushioning springs seated upon said flexible sheet."

10. A resilient seat or bottom for chairs,

couches, etc., comprising a frame having rails, angularbrackets affixed to the :inner J sides of said rails, suspension springs confined Within said brackets, and cushioning springs having a supporting member yoked to said brackets and supported for vertical .movement within said frame by said suspension springs.

In testimony whereof I affix my signature.
